The best islands in the Caribbean for most US travelers are Aruba for reliable dry weather (it sits outside the main hurricane belt), Puerto Rico and the US Virgin Islands if you want to travel without a passport, and Bonaire for shore snorkeling. Saint Lucia and Jamaica are the picks for mountains and rainforest. The right one for you depends less on whose beach looks best in photos and more on the paperwork, fees and plugs that come with each island, so that is how this guide compares them.

How we chose

Most rankings for this search are written by travel advisors and agencies listing their favorite resorts. We took a different route: we compared ten popular islands on facts you can check before you book, taken from official tourism boards, immigration portals, the US State Department, USA.gov and the US Commerce Department’s electric current tables. We did not visit or test anything for this article. Every fee, form and voltage below is listed in the Sources section with the date we checked it (October 2026). Rules change, so confirm on the official link before you fly.

Voltage and plug data come from the US Commerce Department’s table for most islands and from plug reference sites for Bonaire and Curaçao. Some sources list Aruba at 120 V instead of 127 V; either way, standard US plugs fit.

Aruba: best for weather you can plan around

Aruba’s official tourism site says the island lies outside the hurricane belt and has not been directly hit by a hurricane since Atlantic records began in 1851. Hurricane season still runs June 1 to November 30, and passing storms can bring rain or a drop in wind. The tourism board names December to April as the driest peak season.

What to sort before you fly: every traveler, infants included, needs an approved online ED card, which you can fill in within the 7 days before travel. The $20 sustainability fee is paid inside that form by card only (Visa, Mastercard, Discover). Children under 8, cruise passengers and visitors who already paid in the same calendar year are exempt. Aruba’s tourism board warns that third-party sites charge extra to fill in the form, so use edcardaruba.aw.

Skip it if you want rainforest or mountains. Aruba is dry and flat compared with Saint Lucia or Jamaica.

Bonaire: best for snorkeling straight from the shore

The whole coastline of Bonaire is part of the Bonaire National Marine Park. Anyone who enters the sea there, including swimmers who never put on a mask, pays the STINAPA Nature Fee: $40 per person, valid for the calendar year (January 1 to December 31), with children under 13 exempt and cruise passengers paying $10 for one day. You pay online, get a QR code by email, and carry it with ID. The same fee covers Washington Slagbaai National Park, whose entrance is cashless.

Bonaire’s Island Council voted in 2018 to ban sunscreens containing oxybenzone and octinoxate from January 1, 2021. Pack a mineral sunscreen instead (see the gear section below), and if you are comparing reef islands, our Caribbean snorkeling spots guide covers fees and access site by site.

Skip it if you want long soft-sand beaches. Bonaire is built around the water, not the sand.

Power note: Bonaire runs on 50 Hz, and both 127 V and 220 V outlets are in use, which can vary by area or even by hotel. Check device labels for “50/60 Hz” and “100-240 V”.

Curaçao: best for a town worth walking

Curaçao suits travelers who want a historic capital with their beach time. The entry step is the Digital Immigration Card at dicardcuracao.com, required for every person on every trip regardless of age, including children. If you return later, you edit your existing card instead of starting a new one. Holders of US e-passports aged 16 and over can also use the Curaçao Express Pass lane after verifying their passport in the free Airside app within 7 days before arrival.

Skip it if you need US-style power everywhere: like Bonaire, Curaçao runs at 50 Hz with mixed 127 V and 220 V outlets.

Puerto Rico and the US Virgin Islands: best without a passport

USA.gov confirms that US citizens do not need a passport to travel between the mainland and Puerto Rico or the US Virgin Islands. Both use 120 V, 60 Hz power and Type A/B outlets, so nothing in your bag needs an adapter. That makes them the easiest islands for a last-minute trip or for families still waiting on children’s passports. Keep in mind that a day trip onward to a foreign island, such as the British Virgin Islands, brings passport rules back.

The US Virgin Islands add one rule that catches visitors out. Under Act No. 8185, it has been unlawful since March 30, 2020 to use or possess sunscreen containing oxybenzone, octocrylene or octinoxate in the territory, unless prescribed. Check the active ingredients on your bottle before you pack it.

Skip them if you want a place that feels far from home. Chain stores and US dollars are part of the package.

Jamaica: best for culture beyond the resort

Jamaica’s tourism board says US citizens do not need a visa for stays up to 90 days and need a passport valid on entry and exit. All air and cruise arrivals complete the online C5 Passenger Declaration form, which costs nothing and can be submitted up to 30 days before the trip. The board warns against third-party sites that charge a fee for it. For a sense of the island past the beach, read our guide to Jamaican travel and culture.

Power note: Jamaica runs at 50 Hz with 110 V and 220 V supplies, and four plug types are listed. US plugs fit Type A/B sockets, but check frequency ratings on hair tools and anything with a motor.

Dominican Republic: best value for all-inclusive stays

Every passenger arriving or leaving on a commercial flight completes the free E-Ticket form at eticket.migracion.gob.do. You can fill it in as soon as you have flight details, even months ahead, and one form covers up to 7 family members with a single QR code. The country also requires foreign visitors to hold a round-trip ticket; airlines check this before boarding, so one-way bookings with “we’ll decide later” plans don’t work here.

Skip it if you plan to stay in one town without a car or tours. The big resort areas are spread out.

Saint Lucia: best for mountain views and honeymoons

Saint Lucia trades flat white beaches for steep green peaks. The State Department says your US passport must be valid for the length of your stay, and that you need an electronic travel authorization or border form completed online before travel. The bigger surprise is the power: 240 V, 50 Hz and British-style Type G outlets. A US phone charger rated 100-240 V works with a simple plug adapter, but a 120 V-only hair dryer or flat iron does not. Our travel hair dryer guide sorts options by voltage type.

Barbados and Antigua: best for beach variety

Barbados runs at 115/230 V and 50 Hz, with Type A, B, F and H outlets listed. Expect a mix of socket types depending on where you stay.

Antigua and Barbuda has the strictest passport rule in this list: the State Department says your passport must be valid for 180 days after your departure date, and passport cards are not accepted for air arrivals. The island uses 230 V, 60 Hz Type G sockets, so the same adapter you’d pack for Saint Lucia works here.

Gear that the rules above actually call for

Two items solve most of the rule-driven problems in this guide. Neither is needed for every island, so check the table first.

Mineral sunscreen for Bonaire and the US Virgin Islands: Thinkbaby SPF 50+

Thinkbaby’s active ingredient is zinc oxide (23.4% per the Amazon listing), and its ingredient list contains none of the three chemicals banned in the US Virgin Islands: oxybenzone, octinoxate and octocrylene. It is rated water resistant for 80 minutes. It holds 4.6/5 from 25,000+ Amazon ratings (October 2026).

Who it’s for: families and anyone with sensitive skin heading to reef islands with ingredient bans. It’s marketed for babies, but adults use it too.

Who should skip it: people who want a clear, sheer finish. Zinc formulas this strong leave a mark.

  • Pro: Zinc oxide only as the active ingredient, so it avoids the USVI and Bonaire banned filters.
  • Pro: 80-minute water resistance rating, the highest the FDA allows.
  • Pro: Free of parabens, phthalates and avobenzone, per the listing.
  • Con: Amazon’s review summary notes a thick consistency that takes time to spread.
  • Con: Reviewers report a white cast, especially on darker skin, that fades only with thorough blending.

Type G plug adapter for Saint Lucia and Antigua: Ceptics GP-7 (3-pack)

This 3-pack converts plugs to the British Type G sockets used in Saint Lucia, Antigua, Dominica, Grenada and Saint Vincent, all named on the listing. It is grounded and rated up to 250 V and 13 A. It holds 4.5/5 from 8,500+ Amazon ratings (October 2026).

Who it’s for: travelers to Type G islands whose devices are already dual voltage (most phone and laptop chargers say “100-240 V” on the brick).

Who should skip it: anyone heading to Aruba, Puerto Rico, the USVI or the Dominican Republic, where US plugs already fit.

  • Pro: Three adapters, so phone, laptop and camera can charge at once on separate outlets.
  • Pro: Grounded design accepts three-prong plugs.
  • Pro: Small enough to leave in a toiletry bag between trips.
  • Con: It does not convert voltage. A 120 V-only device will be damaged on 240 V, as the listing warns.
  • Con: No USB ports, and each adapter takes only one plug.

How to pick your island

  • Traveling June to November and worried about storms: Aruba, based on its location outside the hurricane belt. Still buy travel insurance; passing storms can affect flights.
  • No passport, or a child’s passport still in processing: Puerto Rico or the US Virgin Islands.
  • Snorkeling is the main event: Bonaire (budget the $40 Nature Fee per adult) or the US Virgin Islands (mineral sunscreen only).
  • Passport expires within six months: avoid Antigua, which needs 180 days after departure; Saint Lucia and Jamaica need validity only for your stay.
  • Bringing a 120 V-only hair tool or CPAP: stick to 120 V, 60 Hz islands (Puerto Rico, USVI) or confirm the device label first. Saint Lucia and Antigua need a converter, not just an adapter.
  • Cruising instead of flying: Aruba’s fee applies only to air arrivals, and Bonaire charges cruise passengers $10 for the day.

FAQ

Which Caribbean island is outside the hurricane belt?

Aruba’s tourism board says the island lies outside the main Atlantic hurricane belt and has not taken a direct hurricane hit since records began in 1851. It can still get rain and calmer winds from storms passing to the north between June and November.

Which Caribbean islands don’t require a passport for US citizens?

Puerto Rico and the US Virgin Islands, per USA.gov. Every foreign island needs a passport for air travel, because US re-entry by air requires one under the Western Hemisphere Travel Initiative.

Do I need a plug adapter in the Caribbean?

Not in Aruba, Puerto Rico, the US Virgin Islands, the Dominican Republic or the Bahamas, which use US-style Type A/B sockets. You need a Type G adapter in Saint Lucia and Antigua, and you may meet Type F sockets in Bonaire and Curaçao.

Do I have to pay to enter Aruba?

Air arrivals pay a $20 sustainability fee through the official ED card, unless they are under 8 or have already paid in the same calendar year. The ED card itself is mandatory for everyone, including infants.
